How to get resource action request information

I'm trying to get any useful information from the payload sent by a Change Lease operation, so I can also adjust the destruction time. My workflow is receiving the payload and several __asd_* inputs, but none of them seem to refer to anything I can use to look up the vm or deployment.

None of these actually refer to a catalog item, catalog item request, or resource action request, as far as I can tell. They all throw 404 errors when I try to look them up with another workflow:

payload.requestId

payload.deploymentId

__asd_catalogRequestId

__asd_correlationId

__asd_requestInstanceId

__asd_targetResourceId

I can go through vRO's browser to find requests and items, and then paste those IDs in to my workflows, and that works.

Any nudge in the right direction would be most appreciated. Thanks in advance!
